IoT Smart Modules : Bluetooth Wifi LoRa Sensor Arduino Module

IoT Smart Modules — Bluetooth, WiFi, LoRa, Sensors and Arduino-Compatible Components

The IoT and embedded development scene has exploded with the rise of LoRa-based long-range networks, Bluetooth Low Energy beacons, ESP32-based WiFi nodes, and gas / environmental sensors for industrial monitoring. This collection covers the IoT modules and sensor components we stock for embedded developers, makers, and IoT product builders — wireless modules (Bluetooth, WiFi, LoRa), environmental sensors (gas, temperature, humidity), Arduino-compatible breakout boards, and supporting passives for prototyping and small-batch production. Sourced through Shenzhen's deep electronics supply chain, with the same logistics infrastructure that delivers our crypto miner parts.

What's in this collection

30+ IoT modules and sensor components organised by use case :

• Wireless communication modules — Bluetooth Low Energy (BLE) modules for short-range device pairing, WiFi modules (ESP-based) for cloud-connected nodes, LoRa modules for long-range low-power wireless sensor networks. Compatible with common microcontroller platforms.
• Environmental and gas sensors — gas-detection sensor modules for industrial air quality, environmental sensing breakouts (temperature, humidity, pressure), motion / proximity sensors for IoT trigger applications.
• Arduino-compatible components — breakout boards and shields compatible with Arduino UNO / Nano / Mega / ESP32 / Raspberry Pi GPIO, ready for direct integration into prototype and small-batch IoT products.
• Supporting passives and accessories — antennas, connectors, breadboard jumpers and prototype-grade components that support module integration during product development.

Who this collection is for

Different audience from our crypto miner parts catalogue :

• IoT product developers building Bluetooth, WiFi or LoRa-connected products and sourcing modules at small-batch quantities (10-500 units) for prototyping and pilot production.
• Embedded engineers and makers evaluating multiple wireless standards and sensor types for new product designs, needing access to a curated selection without sourcing from 5 different suppliers.
• Industrial IoT integrators deploying sensor networks (air quality, asset tracking, environmental monitoring) and needing reliable supply of modules at deployment scale.
• Educational / academic projects equipping labs with IoT teaching kits and Arduino-compatible breakout boards.

Why source IoT modules from LYS Shenzhen

Three reasons embedded developers and IoT integrators standardise on our IoT inventory :

• Direct Shenzhen sourcing — most IoT modules on global e-commerce platforms originate in Shenzhen anyway. Buying direct cuts out the middleman markup, especially relevant at small-batch and pilot production volumes.
• Mixed-order flexibility — combine IoT modules with other components in a single order (especially useful if your IoT product also uses general electronic components from our broader catalogue).
• Worldwide shipping with DDP option for US and EU customers — modules ship fast and clear customs without the friction of larger industrial shipments.

Frequently asked questions

Are these IoT modules tested or just generic Shenzhen surplus ?
We source from established Shenzhen module makers with consistent quality records, not random surplus marketplaces. Each module type has been validated in actual prototype builds before being added to the catalogue. We're not in the business of selling untested modules to developers.

Can you supply datasheets / pinout documentation for the modules ?
Yes. For every module SKU, we can provide manufacturer datasheet, pinout diagram, and basic Arduino / MicroPython example code on request. Send the module name when you order and we'll include the documentation.

I need a specific LoRa frequency variant (433MHz, 868MHz, 915MHz) — can you source it ?
Yes. LoRa frequency variants are region-specific (EU 868MHz, US 915MHz, Asia 433MHz). Specify your target frequency when ordering and we'll source the matching variant. We don't ship the wrong frequency by default.

What's the lead time on bulk IoT module orders ?
Small orders (1-50 units) typically dispatch within a few business days from existing inventory. Larger orders (500+ units) requiring batch sourcing from module manufacturers are quoted with a specific timeline. For production-grade orders we can also support traceability documentation (lot numbers, supplier records) on request.

Do you stock industrial-grade or certified modules (CE, FCC, UL) ?
Module certification varies by manufacturer and SKU. Many BLE / WiFi modules carry the FCC / CE certifications of the underlying chip module (e.g. ESP32-based modules using Espressif's pre-certified module). For specific certification requirements, share your target market and we'll match modules with the appropriate compliance documentation.
